How to directly initialize a HashMap (in a literal way)?

Question

Is there some way of initializing a Java HashMap like this?:

Map test = 
    new HashMap{\"test\":\"test\",\"test\         


        

Answer 1

You can create a method to initialize the map like in this example below:

Map initializeMap()
{
  Map ret = new HashMap<>();

  //populate ret
  ...

  return ret;
}

//call
Map map = initializeMap();
